III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. • There is a segment of Haul Road "A" beyond the Haul Road "H"junction that is no longer actively used. Within TR-45, currently under review, the operator has proposed that this road segment would be modified for postmine use as a segment of the permanent Ridgeline Access Road. If approved, this road segment will need to be partially reclaimed, with roadbed width reduced and cutslope partially backfilled. The existing 36" culvert beneath the road fill across Drainage 006-S1 would logically be retained for the permanent road. This culvert is not depicted on current or TR-45 version of Exhibit 13-2, Surface Hydrology. The map exhibit will need to be properly updated to include the culvert. This item will be included in the Division's adequacy review letter for TR-45. • A haul truck had recently tipped over and a small amount of coal had spilled over the road berm onto the fill slope near the outlet end of culvert K4 (the southern-most Haul Road "K" culvert). The coal spillage needs to be properly cleaned up. 0 Grass seeded last fall on "K" Road cut slopes had very recently germinated in most areas. Necessary maintenance work along the southern-most segment of the Haul Road "K" corridor was described in the Division's November 2003 complete inspection report. Due to seasonal constraints, the work has not yet been conducted. Specifically, the slope immediately down gradient from the toe of the road fill along the lower most segment of the road had been stripped of topsoil, but had not been graded or seeded and some rill erosion had initiated. A small amount of topsoil remains adjacent to this area within a designated temporary stockpile. It is recommended that the slope area ba properly graded, the remaining topsoil from the temporary stockpile be respread over the slope, and the entire area be seeded with the stabilization seedmix. This work should be completed by the end of May. Hydrologic Balance Sediment Pond 005 water level was lapping over the top of the riser. There was a trickle of inflow and a trickle of clear discharge. Pond 006 water level was a couple inches below the top of the primary spillway riser, but there was a small flow of clear water discharging from the primary outlet (approximately 10 gpm). Minor seepage appears to have reinitiated at the seam where the most recent spillway extension was attached. The spillway leak needs to be repaired promptly. Inflow to the pond appeared to be in excess of 50 gpm, much of the flow from the graded spoil area was concentrated in the 006-SE1 drainage. The pre-settling basin has been completely eliminated by backfilling of the "B" Pit.
